Average Cost 0f a Concrete FoundationThe cost of a poured concrete foundation with minimum wall height of 8 feet ranges from $18,500 to $34,000 for sizes from 800 to 1,600 square feet. The minimum cost is higher than our starting Cost of a Block Foundation because that range includes block crawlspaces with a height of less than 4 feet. Walls of a poured concrete foundation are usually 8 feet high, though some homeowners prefer a height of 9 or 10 feet to provide more room for overhead plumbing, wiring and a drop ceiling. Most poured foundation walls are 8 inches thick, but thicker walls might be used when surrounding soils are clay and therefore very heavy when retaining water. The cost of a poured foundation includes professional work from start to finish – excavating the foundation, pouring footings, setting the forms and installing rebar, and of course the concrete walls. Installation also includes adding stable base materials like pea stone for the slab, pouring and finishing the slab and may include the installation of a drain tile or a French drain around the foundation. Waterproofing the exterior of the basement is usually an extra expense but might be included in the poured foundation cost estimate. The same is true for the installation of a sump pump and crock or basin to house it.

The disadvantages are a higher cost for materials and less potential savings by doing it yourself. Is your property suitable for a full foundation?
